Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

For JAM, I would suggest you to keep the basic idea about all the binary system. You should study eutectic and solid solution in detail. For NAT questions, lever rule associated with binary eutectic and solid-solutio is very important and you should practice questions from that part.
